I looked at these options when I was buying the rMBP. Benchmarks had it about 8% better in terms of CPU performance, but real world I am not sure if the benefit is there. (unless you are doing some significantly major CPU usage work)

In Engadget's awesome review,

Geekbench 11,591 11,082

The 11,082 belongs to the 2.3, and 11,591 belongs to 2.6. The 2.7 scores at about 11,800.

Depending on your usage, even the 2.3 might be good enough, with 16GB ram of future-proofing.

Note, battery life is better on the 2.3 then the other models,
according to engadget

"Despite all that performance, we were still impressed by the battery life. In our standard rundown test, which involves looping a video with WiFi on and the display set at a fixed brightness, we netted an impressive seven hours and 49 minutes on the 2.6GHz model. The 2.3GHz model lasted an average of nine hours and 22 minutes -- a runtime so long we at first thought it was a fluke. After repeated runs, though, we kept turning up similar results."
